Stewart said Obama has now lent a hand to every "tin-foil behatted" conspiracy theorist.

"Well, congratulations, President Barack Obama," Stewart said. "Conspiracy theorists, who generally can survive in anaerobic environments, just had an algae bloom dropped on their f—ing heads — thus, removing the last arrow in your pro-governance quiver: Skepticism about your opponents."

Stewart also tore into the IRS for trying to issue only a simple apology after their disclosure. Stewart harped on an IRS spokesperson's aside on a conference call with reporters that she was not very good at math.

"That's a good one!" Stewart said, addressing her as "lady who works at the place that calculates people's taxes."

"You've managed to show that when the government wants to do good things, your managerial competence falls somewhere between David Brent and a cat chasing a laser pointer," Stewart said. "But when government wants to flex its more malevolent muscles, you're f—ing Iron Man."
